2015-01-01T16:55:06ZFalseFalseEfficiency of conventional thermal electricity generation Output from conventional thermal power stations consists of gross electricity generation and also of any heat sold to third parties (combined heat and power plants) by conventional thermal public utility power stations as well as autoproducer thermal power stations. The energy efficiency of conventional thermal electricity production (which includes both public plants and autoproducers) is defined as the ratio of electricity and heat production to the energy input as a fuel. Fuels include solid fuels (i.e. coal, lignite and equivalents, oil and other liquid hydrocarbons, gas, thermal renewables (industrial and municipal waste, wood waste, biogas and geothermal energy) and other non-renewable waste.
Units: Fuel input and electrical and heat output are measured in thousand tonnes of oil equivalent (ktoe) Efficiency is measured as the ratio of fuel output to input (%)
The majority of thermal generation is produced using fossil fuels but can also include biomass, wastes, geothermal and nuclear. Associated environmental impacts at the point of energy generation are mainly related to greenhouse gas emissions and air pollution. However, other environmental impacts, such as land use change, biodiversity loss, ground water pollution, oil spills in the marine environment, etc, occur during upstream activities of producing and transporting the primary resources or final waste disposal. Whilst the level of environmental impact depends on the particular type of fuel used and the extent to which abatement technologies are being employed, the greater the efficiency of the power plant, the lower the environmental impact for each unit of electricity produced (assuming that the increase in efficiency leads to an absolute decrease of fossil fuel input). Environmental context
The indicator shows the efficiency of electricity and heat production from conventional thermal plants. A distinction is made between public (i.e. main activity producers), thermal plants and autoproducers. Public thermal plants mainly produce electricity (and heat) for public use. Autoproducers produce electricity (and heat) for private use, for instance in industrial processes.
The efficiency of electricity and heat production is an important factor since losses in transformation account for a substantial part of the primary energy consumption (see ENER 36). Higher efficiency of production therefore results in substantial reductions in primary energy consumption, hence reduction of environmental pressures due to avoided energy production. However, the overall environmental impact has to be seen in the context of the type of fuel and the extent to which abatement technologies are used.
Compliance with environmental legislation (for example the Large Combustion Plant Directive 2001/80/EC, the CARE package, etc) requires the application of a series of abatement technologies (e.g. to reduce SO 2 emissions requires retrofitting the plant with flue-gas desulphurisation technology, carbon capture and storage to capture CO 2 emissions, etc) increasing the energy consumption of the plant, thus reducing its efficiency. This is why it is important to promote highly efficient generation units, such as IGCC (Integrated Gasification Combined Cycle), which can operate at higher efficiencies.
Policy context
The Directive 2012/27/eu on energy efficiency establishes a common framework of measures for the promotion of energy efficiency within the European Union in order to achieve the headline target of 20% reduction in gross inland energy consumption. Member States are requested to set indicative targets. It is up to the Member states whether they base their targets on gross inland consumption, final energy consumption, primary or final energy savings or energy intensity.
Council adopted on 6 April 2009 the climate-energy legislative package containing measures to fight climate change and promote renewable energy. This package is designed to achieve the EU's overall environmental target of a 20 % reduction in greenhouse gases and a 20 % share of renewable energy in the EU's total energy consumption by 2020. The climate action and renewable energy (CARE) package includes the following main policy documents:
Directive 2009/29/ec of the European parliament and of the Council amending directive 2003/87/ec so as to improve and extend the greenhouse gas emission allowance trading scheme of the community
Directive 2009/31/ec of the European parliament and of the Council on the geological storage of carbon dioxide
Directive 2009/28/ec of the European parliament and of the Council on the promotion of the use of energy from renewable sources
Communication from the Commission; COM(2008) 771 final. The main objectives of this communication are to report on the current status of the combined heat and power generation (CHP or cogeneration), and to present possibilities for its development.
Detailed guidelines for the implementation and application of Annex II to Directive 2004/8/EC; 2008/952/EC. Guidelines for the calculation of the electricity from high-efficiency cogeneration
Directive 2010/75/eu of the European Parliament and of the Council on industrial emissions (integrated pollution prevention and control) recast. The Directive establishes a general framework for the control of the main industrial activities in order to prevent, reduce and as far as possible eliminate pollution arising from industrial activities in compliance with the ‘polluter pays’ principle and the principle of pollution prevention.
Average annual rate of growth calculated using: [(last year / base year) ^ (1/number of years) - 1]*100
Efficiency of electricity and heat production = (electrical output + heat output)/fuel input The coding (used in the Eurostat New Cronos database) and specific components of the indicator are:
Numerator:
Electricity output from conventional thermal power stations 101101 (6000 electrical energy) + Heat output from conventional thermal power stations 101101 (5200 derived heat)
Electricity output from public thermal power stations 101121 (6000 electrical energy) + Heat output from public thermal power stations 101121 (5200 derived heat)
Electricity output from autoproducer thermal power station 101122 (6000 electrical energy) + Heat output from autoproducer thermal power station 101122 (5200 derived heat)
Denominator:
Input to conventional thermal power stations 101001 (0000 all products)
Input to public thermal power stations 101021 (0000 all products)
Input to autoproducer thermal power stations 101022 (0000 all products)

Eurostat metadata for energy statistics http://epp.eurostat.ec.europa.eu/portal/page/portal/statistics/metadata
Geographical coverage: The Agency had 32 member countries at the time of writing of this fact sheet. These are the 27 European Union Member States and Turkey, Iceland, Norway, Liechtenstein and Switzerland. Total: Norway, displays efficiencies higher than 100% for thermal generation due to the extensive use of electric boilers for heat production. In the Eurostat statistics, the heat is included in the output, while the electricity input is not. For power plants the consumption of electricity is attributed to the energy sector while partly may be in fact used as input for heat. For these reasons, Norway was excluded from the calculations
Public: Norway is excluded as the data was considered unreliable, giving efficiencies ≥ 100%. Autoprocucers: Bulgaria, Greece, Lithunia, and Slovenia are excluded as they were considered unreliable, giving efficiencies ≥ 100%. No autoproducers data was available for Cyprus, Iceland and Malta
Temporal coverage: 1990-2010.
The efficiency of electricity production is calculated as the ratio of electricity output to the total fuel input. However, the input to conventional thermal power plants cannot be disaggregated into separate input for heat and input for electricity production. Therefore the efficiency rate of electricity and heat production equals the ratio of both electricity and heat production to fuel input, which assumes there is an efficiency rate for heat production. Also, electricity data (unlike that for overall energy consumption) for 1990 refers to the western part of Germany only, so there is a break in the series from 1990-1992. Strengths and weaknesses (at data level) Data have been traditionally compiled by Eurostat through the annual Joint Questionnaires, shared by Eurostat and the International Energy Agency, following a well established and harmonised methodology. Methodological information on the annual Joint Questionnaires and data compilation can be found in Eurostat's web page for metadata on energy statistics.
